To (zZ/ 107mm it may concern.'

Be it known that I, Tnnnsrironu BABIN, a citizen of the United States,residing at Houma, in the parish of Terrebonne and State of Louisiana,have invented a newT and useful acetylene-Gas Generator; and 1 do herebydeclare the following to be a f ull, clear, and exact description of theinvention, such as will enable others skilled in the art to which itappertains to make and use the same.

This invention relates to a new and useful acetylene gas generator.

As one of the objects of the invention, it is the aim to improve thestructure of the acetylene gas generator, shown, set forth, and claimedin the Patent No. 843,429,

Another object of the invention is to provide an apparatus of thisnature, simple, efficient, and practical in construction, and one whichmay be easily operated.

The invention comprises further features and combination of parts, ashereinafter set forth, shown in the drawings and claimed.

In the drawings a Figure 1 is a view in side elevation of the improvedacetylene gas generator constructed in accordance with the invention.

Fig. 2 is a vertical sectional view through the generator.

Referring more particularly to the drawings 1 designates the gasgenerator tank, while 2 denotes the gas reservoir, which includes thegasometer bell 3. Arranged in the gas generator tank is a bell 4, underwhich and above the water the gas is generated. This bell 4 terminatesat its upper portion in a supplemental casing 5, forming a carbidchamber 6, which is provided with a conical bottom 7 The casing 5 isprovided with an opening 8, through which the carbid may be introducedinto the chamber 6. This opening 8 is closed by athreaded plug 9. Theconical bottom 7 of the carbid chamber is provided with an opening 10 atits apex, which is normally held closed by the valve or closure 11. Thisvalve or closure is constructed upon the upper end of a rod 12,

5 is a sectional view on line 5-5 of The lower end of the rod has aplate 13 secured to it.

The pipe 14 has its upper and lower ends open, and when the gas in thebell decreases, the bell lowers and the lower end of the pipe 14 extendsinto the water, thereby sealing the lower end of said pipe. However,when the gas increases in the bell 4, the bell rises, and should the gasincrease enough to raise the bell sufficiently to cause the lower end ofthe pipe 14 to assume a position above the level of the water, theexcessive gas will escape through said pipe 14. Passing through pipe 15is a rod 16 terminating in a laterally extending portion 17, which inturn is provided with a forked end 1S, in which the lower flat end plate13 is secured by the pin 18a. The flat plate on its opposite flatsurfaces lits exceedingly close between the forks 18, as shown in Fig.3, while the edge 1Sb of the plate 13 engages the crotch 13a exceedinglyclose as shown in Fig. 2, so as to support the rod 12 with rigidity atright angies to the portion 17. To start the generation of gas, th-e rod16 is shaken or twisted, which will, owing to its laterally extendingportion at its lower end, rock the closure or valve in the carbidchamber, thereby allowing a few grains or particles of carbid to fail inthe iifater of the tank 1, after which, by raising the rod 16 slightly,the closure or. valve may be slightly opened, in order to allow afurther charge of carbidto fall in the water. As the carbid falls in thewater, gas is generated, which causes the bell 4 to ascend. As the gasis generated, it escapes from the bell 4 through the pipe 20. As the gasleaves the bell 4, the bell 4 gradually lowers. Threaded upon the upperportion of the rod 16 is a nut 21, adapted to engage the other end ofthe pipe 15, in order to support the rod 16, thereby holding the valveor closure in the carbid chamber in an open position. By screwing thenut 21 downwardly or upwardly, the closure or valve of the carbidchamber may be held in different positions. Secured to the pipe 15 uponthe exterior of the bell 4 is a sleeve 22 having a laterally extendingear 23, in which a link 24 is pivoted.

The acetylene gas generator when not operating has its valve 11 closed,the nut 21 of the rod 16 is screwed tight against the upper end of thepipe 15, and is held against pipe by inserting the hook 26 of thetubular rod 25 (which is adjustably threaded to the link 24) into theaperture 27 of the rod 16, thereby holding the nut 21 jammed against theupper end of the pipe 15. vWhen the generator is to be operated, thehook 26 is removed from the aperture 27, after which the nut 21 isadjusted, so that the rod 16 will rise telescopically through the pipe15, in which case the valve 11 will open, as shown in Fig. 2, owing tothe valve rod 12 being pivoted to the lower end of the rod 16. After soopening the valve 11, the tubular rod 25 may be adjusted upwardly, sothat the hook 26 will register with and enter the aperture 27, therebyholding the valve so opened. Said valve may be opened to any desiredposition. Vhen the valve is to be closed, the nut 21, afterdisconnecting the hook 26, is so turned or rotated, that the rod 16 willlower, in which case the valve 11 will correspondingly lower and becomeclosed, in which case, the' hook 26 may be returned in engagement withthe aperture 27. ln order to prevent the rod 16 from being furtherraised, the tubular rod 25 may be extended by unscrewing the same withrelation to the link 24, sulliciently to allow the hook 26 to enter theaperture 27. An additional pipe 29 is arranged on the interior of thebell 4, and terminates upon the exterior. Extending through the pipe 29is a rod 30, to the upper end of which a laterally extendingl lever 31is pivoted, while to the lower end a scraper blade 32 extendinglaterally, is pivoted. By rocking the rod by manipulating' the lever 31,the scraper blade will dislodge the sediment in the bottom of the tank1, and by removing the plug 33 (which is threaded in the tank 1 adjacentits bottom), the sediment and the like may be drawn oil' from thetank 1. The tank 1 may be supplied with water, thro-ugh the spout 34,there being perforations in the side of the tank to allow the water toenter. The gas pipe 20 threads into an elbow 35, which in turn isthreaded to the union 36. This union 86 threads into an elbow on theexterior of the tank 1, there being flange `members 38 threaded orotherwise secured, one upon the interior and one upon the exterior ofthe tank 1. Tn this manner a water tight connection is provided.Threaded to the elbowf', 37 is a. drain valve 39, serving to permit,drainage of any water that may accumulate"d in the pipes 20, 36 and 42.The elbow 3 is connected to the valve casing 40 (in whicl a valve 41 isarranged) by virtue of th union 42. The valve casing 40 is in turconnected to a short length of pipe 43, be p tween which and a similarpipe 44 a unio 45 is connected. This union 45 comprise the parts 46 and47 held together by the;

member 48, which is threaded to the part@ 47. The pipe 44 is threadedinto an elbow 49 on the exterior' et1 the tank 2. 49 is connected to aunion 50, which in turn threads into the elbow 51 on the interior of thetank 2, there being flange members 52 and 53 threaded into the wall ofthe tank 2, one upon the exterior and one on the interior. Threaded toand rising from the elbow 51 upon the interior of the bell 3 is a gaspipe 54, which terminates at its upper portion in an overhanging gooseneck 55, which comprises the elbows 56 and 57, the nipple 58 and theextension pipe 59. This gas pipe 54 conveys the gas into the reservoirtank 2, and under the gasometer bell 3 et the tank 2. The gas under thegasometer bell is carried oill by way of the pipe 60, which is securedto the tank 2 of the gas reservoir, in a manner similar to theconnection of the gas pipe in the tank 1. A. T-union 62 with which thepipe 6() connects, as shown, is provided with a drain valve 63, in orderto drain the gasometer bell of the excess gas, especially when a certainnumber of burners or jets or the like (not shown) which are adapted tobe connected to the gas discharge pipe 65 are cut oii, prior toregulating thev carbid from the carbid chamber or container. The tank 2is supplied with water, by way of the pipe 66. Threaded to a union 67 onthe exterior of the tank 2 is an elbow 68 having a pipe extension 69.This elbow 68 may be rocked downwardly or upwardly, and is adapted tocarry ott the overtlow ot water in the tank 2. In other words, byarranging the extension pipe 69 substantially horizontally, the water inthe tank 2 will not rise any farther than the nipple 67, for the waterwill be carried ofi by way of the extension pipe 69, as well as by theunion 67. By arranging the extension pipe 69 at an angle toward an uppervertical position, or exactly to an upward vertical position, the waterin the tank 2 may be increased in its height. Tn order to regulate thesupply of water to the tank 2, the pipe 66 is provided with a valve ofthe usual construction, designated by the numeral 70.

The upper portion of the gasometer bell 3 is provided with a handle 71,whereby the bell may be manually raised or lowered. Forming a part ofthe handle 71 is an eye 72, in which the angled end 73 of a rod 74 isarranged. This rod 74 is in turn pivot-ally connected at 75 to a rod 76,which in turn is connected at 77 to the valve 41. It will be seen thatby this connection between the gasometer bell and the valve 41,communication between the gas pipe 20 of the gas tank 1 and the gas pipe54 ot the tank 2, is automatically controlled, as the gasometer bell 3rises and falls. Tn other words the normal position of the gasometerbell 3 is downwardly and as the gas is generated in the tank 1, the sameis carried oli by'way This elbow of the pipe 20, through the passage-waybetween the two tanks, and under the gasometer bell, by way of the gaspipe 54. As the gas accumulates under the gasometer bell, the saineascends, and when it reaches a certain position during its ascension,communication between the two tanks 1 and 2 is automatically cut oli',by virtue of the valve l1. As the gas under the bell is consumed, thebell lowers or descends, which also tends to force the gas out throughthe pipe 60.

1n using this form of acetylene gas generator, the valve 11 is set oropened just sui'iiciently to allow a requisite quantity of carbid tofall or feed into the water, so as to maintain just a trifle more of gasin the gasometer bell a than enough to supply a certain number of jets,and as the gas is cut off at one, two or three jets, said valve isre-regulated, hence the provision of the means, whereby the valve may beadjusted the slightest degree and held so adjusted. lVhen the gas is cutoli from all the jets, the llow of the carbid is cut olf, therefore thegeneration of gas ceases. For instance, if tiiere are ten jets to besupplied with gas, for a period of ten to fifteen hours, then the valve11 is set, in order to feed a requisite amount of carbid, in order togenerate just a trifle more of gas, than is required for the ten jets.rtherefore, for ten to fifteen hours the acetylene generator would notrequire a constant attendant.

The operation of the generator is as follows:

The tanks 1 and 2 are filled with water in the usual manner to thedesired height. The bells 3 and a are placed in their respective tanks,and the carbid chamber 6 filled with carbid through the opening 8, firsthaving removed the plug 9. By raising the rod 16 a mere trilie, thevalve 11 will be unseated, owing to the valve being connected to the rod16. After the rod 16 has been so raised the nut 21 is set, as shown inFig. 2, preventing the rod from descending. T hen by adjusting thetubular rod 25 relative to the link 241;, the two of them being threadedtogether, the hook 26 is placed in engagement with the aperture 27 atthe upper end of the rod 1G. 1n this manner the valve 11 is heldslightly opened, thereby permitting a flow of carbid into the water ofthe tank 1, which water, owing to the pipo 14 opening to the outsideatmosphere enters up into the bell il. lThe gas is generated in the bellland passes down through the pipe 2O and through the connections (whichincludes the valve 41) into the gasometer bell 3 by way of the pipe 54Eand the goose neck 55. Since the pipe (which extends up into the bell 3)is connected to the service or discharge pipe 65, the gas may be carriedoff to be consumed for any suitable purpose such as lighting. 1f thereis an excessive amount of gas in the bell 3 the same may be drained byvirtue of the valve 63. Also if there is an excessive quantity of gas inthe bell a it may also be drained by virtue of f1' the valve 39. As thegas is generated and passes into the bell 3 in excess to the consumptionor utilization of the gas by way of the service pipe, the bell 3 willascend sutliciently in order to close the valve 4:1, owing to theconnections 72, 73, 7e and 75, and 7 6 and 77 between the valve al andthe bell 3, thereby cutting off the gas from passing from the bell a tothe bell 3, which will cause the bell 3 to lower, which will re-open thevalve fil. As in the operation of all acetylene gas generators anattendantv is to be in charge of the present form of apparatus, and inthis case, when the consumption of gas is less than the generation ofthe same, which will cause the bell 4 to rise to such a position thatthe lower end of the pipe la will be above the4 level of the water inthe tank 1, thereby causing the escape of gas into the room in which thegenerator is contained, the duty of the attendant is to close the valve11, by adjusting the nut 21 and the tubular rod 25 accordingly, to notonly close the valve 11, but to hold the same closed, thereby cuttingolf the flow of the carbid. Another way for obviating the escape of thegas into the room is to provide some suitable connection (not shown)between the valve 39 and the outdoor atmosphere, in order to drain thebell of the eX- cess gas. The sludge or sediment that may accumulate inthe bottom of the tank 1 may be stirred by the device 32, by operatingthe handle 31.
